Question

the cash difference between selling a shirt at a profit of 10% and 15% is rupees 10 what are the two selling prices.

Answer 1

let cp be x . then sp at 10% gain sp=100+10*x/100=11x/10rs again at 15%gain sp=100+15*x/100=115x/100.
since difference is 10rs so 115x/100-11x/10=5x/100
5x/100=10, then x=200rs
now 1st sp=11x/10=11*200/10=220rs and
2nd sp=115x/100=115*200/100=230rs.
1st sp is 220and 2nd sp is 230

Answer 2

Difference between profit: 5 percent

5 percent profit = 10 rupees
100 percent profit =200 rupees
Price of shirt = (200÷2) rupees
=100 rupees

Price of shirt at 10 percent profit=110 rupees

Price of shirt at 15 percent profit =115 rupees
